hello I just got an email saying, "your application for permanent residence in canada appears to be ready for visa issuance. Your permanent residence visa can only be issued at detroit office...." then the email provides two mailing addresses, one for detroit, michigan (for us residents) and the other for windsor, ontario (for canadian residents). I'm confused as the letter specifically said visa can only be issued at detroit office. Please any advice is appreciated. Also, the letter did not mention anything about the rprf. when do I send the fee? after the visa is issued? or should i send the cheque along with the passport? i live in windsor, canada but do not have a us visa. Can I send a friend with authorization letter to get the passport stamped? please guys help me out here.....
